Embodiment approach 1 and 2

[0036] 1. Decorative board for floor material and decorative material for floor according to Embodiment 1

[0037] In the decorative board for flooring materials according to Embodiment 1, at least a pattern layer, a transparent adhesive layer, and a transparent polypropylene resin layer having a thickness of 150 to 500 μm are sequentially laminated on a base plate made of polyolefin resin. layer and a transparent surface protection layer made of ionizing radiation curable resin.

[0038] Substrate board

[0039] As the base plate, a plate made of polyolefin resin is used. Usually, a film composed of polyolefin resin can be used.

[0040] The polyolefin resin is not particularly limited, and resins generally used in the field of decorative panels can be used. For example, polyethylene, polypropylene, polybutene, polymethylpentene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ethylene-propylene-butene copolymer, polyole...

Embodiment 1

[0153] (Manufacture of decorative panels for floor materials)

[0154] A 60-μm-thick colored polypropylene having a corona discharge treatment applied to both surfaces was prepared as a base plate F. On one side of the substrate sheet F, it is formed with a solid weight of 2 g / m by the gravure printing method 2 Polyurethane-cellulosic resin (resin composed of 5 parts by weight of 1,6-hexamethylene diisocyanate added to a mixture of 100 parts by weight of carbamate and nitrocellulose) was applied to form the bottom layer G on the back.

[0155] On the surface opposite to the surface on which the back primer layer G is formed, it is formed at a solid content of 2 g / m by gravure printing 2 Coating acrylate-polyurethane resin (resin composed of 5 parts by weight of 1,6 hexamethylene diisocyanate added to 100 parts by weight of acrylate polyol) to form a bottom layer for printing (not shown).

[0156] On the bottom layer (not shown) for printing, use the gravure printing method t...

Embodiment 2～3 and comparative example 1

[0168] As shown in the following Table 1, the thickness of the transparent polypropylene-based resin layer was changed, except that it was performed in the same manner as in Example 1, and a floor decorative material was produced.

Abstract

The present invention provides a decorative board for floor materials capable of exhibiting good scratch resistance, caster resistance, impact resistance, etc. without forming a backing layer, and a decorative floor material using the same. Specifically, the present invention provides a flooring material composed of sequentially laminating a decorative layer, a transparent polyolefin resin layer having a thickness of 150 to 500 μm, and a transparent surface protection layer on a base plate made of polyolefin resin. A decorative board and a decorative material for floors using the same.

Description

technical field [0001] The present invention relates to a decorative board for floor materials and a decorative material for floors using the same. [0002] The decorative material for flooring of the present invention is useful as a flooring material in buildings such as individual houses, apartments, condominiums, nursing homes, and stores, for example. Background technique [0003] At present, as a decorative material for flooring materials, it is widely known that a wooden decorative veneer is laminated on a wooden plywood, and a material for coating is laminated. Veneer, finished material. [0004] However, the wooden decorative veneer is a substance that thins natural wood, and it is desired to control the use of natural wood in consideration of the depletion of wood resources and the global resource conservation movement. Therefore, in recent years, instead of the wooden decorative veneer of natural wood, a decorative board artificially expressed by printing a wood ...
